It is well known that bacteria and other microorganisms contain enzymes that can repair UV-damaged DNA, a process known as 'reactivation'. Some of these enzymes need visible light to perform the repairs ('photoreactivation'), while others can do so without light (known as 'dark repair'). Photoreactivation is generally quicker than dark repair, but both of these phenomena pose obvious problems ...

Hanovia has just launched its new Quantum in-line medium pressure UV system. This low-cost device is designed specifically for small-flow industrial process water applications (up to 120 m3/hr) in the food, beverage, brewing, pharmaceutical and electronics industries. It is also ideal for treating water in small pools or spas. It was developed using high-end CFD* modelling software and meets ...

UV disinfection technology is fast becoming one of the most popular methods of destroying pathogenic microorganisms in wastewater. Not only is it a low cost technology, it does not produce any of the toxic by-products associated with conventional chlorine-based disinfection. An important factor that designers of UV systems have to take into account, however, are fluctuations in wastewater ...
